摘要： An electric-parking-brake for a utility-vehicle, including: a feed-line for brake-pressure air; a discharge-line for brake-pressure air for a pneumatic-brake-device; a first-valve and a second-valve, each being switchable between a stable-state and an activated-state in response to electrical control-signals; and a valve-device which is connected between the feed-line and the discharge-line and exhibits a control-input, the valve device being switchable between a stable-state and an activated-state in response to control signals at the control-input, the feed-line being connected to the discharge-line in the activated-state, in which the first-valve in the stable-state or in the activated-state connects the control-input of the valve-device to the discharge-line, to retain a current-state of the valve-device when the brake-pressure air is applied to the discharge-line, and in the activated or stable state connects the control-input to the second-valve. Also described are an electric parking brake system, a utility vehicle, and a related method.

摘要： A circuit arrangement for detecting a solenoid valve type in vehicles, including at least one solenoid valve in the circuit arrangement for detecting the solenoid valve type and having at least one coil winding having a resistance of the typical order of magnitude for a predetermined vehicle electrical distribution system supply voltage, a constant current source, arranged to impress a predetermined measurement current into the one coil winding of the solenoid valve, a current mirror circuit, arranged to generate a second voltage on a detection section of the circuit arrangement from a first voltage produced as a result of the impressed measurement current on the at least one coil winding of the at least one solenoid valve, in which the second voltage produced on the detection section is passed out, on the detection section, directly to a microcontroller in a control device for determining the type of solenoid valve.

摘要： A method and computer program for electronically regulating the brake force distribution in a pressure medium-operated brake system of a vehicle having at least one front axle brake circuit, associated with a front axle, and at least one rear axle brake circuit, associated with at least one rear axle, in which when the brake system is operated, a rear axle brake pressure, acting in the at least one rear axle brake circuit, is regulated to prevent locking of the rear wheels before locking of the front wheels, and in which the brake pressure at the rear axle is limited only while a pressure value which acts in the rear axle brake circuit is below a prespecified pressure threshold value, but the brake pressure at the rear axle is not limited if the pressure value acting in the rear axle brake circuit is not less than the prespecified pressure threshold value.

摘要： A solenoid valve apparatus for a brake system for a vehicle, including: a main valve unit; a pilot-control valve unit that is fluidically connected to the main valve unit; and a housing to accommodate at least the main valve unit and the pilot-control valve unit; in which the pilot-control valve unit includes a double solenoid unit and at least one valve device, in which the double solenoid unit is formed such that it can be populated with at least one valve device, and in which the double solenoid unit has at least two accommodating portions for accommodating valve devices and at least two solenoid devices for actuating valve devices. Also described are a related braking system and a related method for mounting a solenoid valve assembly for a braking system for a vehicle.
